Using DBCA to Create an Oracle RAC One Node Database

Configure Oracle RAC One Node database using Oracle DBCA after creating a software-only setup of Oracle RAC software on cluster nodes.

After installation of Oracle Real Application Clusters (Oracle RAC) software, start Oracle Database Configuration Assistant (Oracle DBCA).

1. From the Database Operation page, select the option Create Database.
2. On the Creation Mode page, select Advanced Configuration.
3. On the Deployment Type page, select Oracle RAC One Node database.

   Selecting one node deploys Oracle RAC One Node on a single node. Oracle recommends that you select all nodes in the cluster to which you want Oracle RAC One Node to be able to fail over.

When you use DBCA to create an Oracle RAC One Node database, a failover service is automatically configured.
